I Need An Expert On The Stella

Here's the front

I hadn't seen this "coiled hair" version before, but one thing jumps out at me -- there should be a period before the "3", like there is before the "7" around the rim. The spacing and the size of the lettering looks a little off as well -- the "S"s, "G" and "3" are bigger than the "A" and "7"s, for example.

Here's a proof version of the 1879 coiled hair, but you can see the differences, front and back: http://www.PCGScoinfacts.com/Coin/Detail/88058

Unfortunately, it appears you have a fake.

When examining any modern coin that has a portrait, look carefully at the facial features and compare with a clear image of a known genuine example.

To do this, it is even a good idea to put the image of both coins alongside each other on a computer screen to the same scale, so that visual comparison becomes much easier.

We are all programmed from birth to develop a strong ability recognize facial features; that is important to our survival, both as babies and as grown adults.
It can be put to good use to help in the detection of fakes.
